The Weston Price Foundation is a huge promoter of the dairy and meat industry. (competition) Soy foods threaten these industries' profits of course.

Cow's Milk vs. Soy Milk

Other anti-soy crusaders, most notably the U.S. dairy industry, clearly have a financial agenda. In recent years, the dairy industry has been waging war against soymilk. They have attempted to keep soy beverages from being included in the milk group in the Dietary Guidelines for Americans. They have sued the manufacturers of soy beverages for using the word milk, claiming that the dairy industry alone has a right to use the term. And they have tried to keep soy beverages from being sold alongside cow's milk in the grocery aisles. A spokesperson for the National Milk Producers Federation made it clear why the industry was upset. "It is," he said, "a clear attempt to compete with dairy products."

Meanwhile, the dairy industry spends hundreds of millions of dollars on ads and other forms of promotion trying to convince the public that cow's milk is vastly preferable to soymilk. For example, the Dairy Bureau tells you about the nutritional comparison between cow's milk and soymilk. "Unfortified soy beverages," they say, "contain only half of the phosphorus, 40 percent of the riboflavin, 10 percent of the vitamin A, (and) 3 percent of the calcium . . . found in a serving of cow's milk." Let's look at this carefully for a moment.

Only half the phosphorus? Brenda Davis is a registered dietitian and former Chair of the American Dietetic Association's Vegetarian Practice Group. She is not impressed by the dairy industry claims. "We get plenty of phosphorus in the diet," she says, "and possibly even too much. Providing only half the phosphorus of cow's milk is an advantage, not a disadvantage."
Only 40 percent of the riboflavin? It's true that unfortified soymilks contain only about half as much of this nutrient as cow's milk, but riboflavin is plentiful in nutritional yeast and green leafy vegetables, and is found in nuts, seeds, whole grains, and legumes, so getting enough riboflavin isn't a problem for people who eat a variety of healthy foods. In fact, vegans (who consume no dairy products) consume as much, or nearly as much, of this vitamin as lacto-ovo vegetarians and non-vegetarians. A mere teaspoon of Red Star Nutritional Yeast powder contains as much riboflavin (1.6 mg) as an entire quart of cow's milk.
Only 10 percent of the vitamin A? Vitamin A is plentiful in plant-based diets. We don't need milk to get sufficient amounts of this nutrient. In fact, vitamin A deficiency is quite rare among North Americans and Europeans who eat plant-based diets. Furthermore, vitamin A is high in cow's milk only because it's added to it, and there is no reason it could not be added to non-dairy beverages if there was some advantage to doing so.
Only 3 percent of the calcium provided by cow's milk? Where does the dairy industry come up with this stuff? All of the most popular soy beverages sold in the United States provide vastly more calcium than the 3 percent claimed by the Dairy Bureau. Westsoy Plus provides 100 percent as much; Vitasoy Enriched provides 100 percent as much; Pacific Soy Enriched provides 100 percent as much; and Edensoy Extra provides 67 percent as much. Even those soy beverages that have not been enriched provide two to nine times as much calcium as claimed by the Dairy Bureau.
Meanwhile, there are a few more things the dairy industry isn't telling you about the nutritional comparison between cow's milk and soymilk. For example:

Cow's milk provides more than nine times as much saturated fat as soy beverages, so is far more likely to contribute to heart disease.
Soy beverages provide more than 10 times as much essential fatty acids as cow's milk, and so provide a far healthier quality of fat.
Soy beverages are cholesterol-free, while cow's milk contains 34 mg of cholesterol per cup, which again means that cow's milk is far worse for your heart and cardiovascular system.
Soy beverages lower both total and LDL ("bad") cholesterol levels, while cow's milk raises both total and LDL cholesterol levels, providing yet more reasons soymilk is better for your health.
Soy beverages contain numerous protective phytochemicals that may protect against chronic diseases such as heart disease and osteoporosis. Cow's milk contains no phytochemicals.
Men who consume one to two servings of soymilk per day are 70 percent less likely to develop prostate cancer than men who don't.
